There's really only a couple of things that are the same with everybody. First being you need a lot of carbs when bulking up and second you'll need more protein when dieting hard then you would when you are bulking. This is because carbs are protein sparing.

There's a load of bro-science behind all this, but ultimately just make sure you get > 100 g protein a day and keep your calories around 2,000 - 2,500/day. Whatever macro breakdown makes it easiest for you to stick with your diet is the right one for you. For instance, I tried keto twice and both times I hated it. I do much better on 40/40/20, but some people swear by keto.

The most important things are (1) adequate protein and (2) total calories. The rest is just preference.
